Inter-integrated circuit interface (I
Up to two I
standard (up to 100 KHz), fast (up to 400 KHz) and fast mode + (up to 1 MHz) modes.
Both support 7-bit and 10-bit addressing modes, multiple 7-bit slave addresses
(2 addresses, 1 with configurable mask). They also include programmable analog and
digital noise filters.
Table 4.
In addition, they provide hardware support for SMBUS 2.0 and PMBUS 1.1: ARP capability,
Host notify protocol, hardware CRC (PEC) generation/verification, timeouts verifications and
ALERT protocol management. They also have a clock domain independent from the CPU
clock, allowing the I2Cx (x=1,2) to wake up the MCU from Stop mode on address match.
The I2C interfaces can be served by the DMA controller.
